Why teams connect SendGrid and Smartrecruiters
Keep the people, teams, and status that SendGrid and Smartrecruiters share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.
Each tool in SendGrid keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Smartrecruiters is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.
Stacksync syncs Contacts, List, Segments, Categories in SendGrid with Jobs, Job Postings, Interviews, Offers in Smartrecruiters bi-directionally and in real time. A person added, moved, or offboarded in Smartrecruiters creates or updates the matching user in SendGrid within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where SendGrid captures details of its own, such as a corrected contact or a login identity, those can flow back to Smartrecruiters in whichever direction you configure.
Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.
Common use cases
- 01 Reconcile transactional email activity with support tickets so agents see what a customer was sent
- 02 Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
- 03 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.
- 04 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.
Common sync patterns
Org and team structure kept current
Department, team, and reporting-line changes from Smartrecruiters keep the groups, queues, or projects in SendGrid assigned to the right people.
Where SendGrid routes or assigns work by person: assignments follow the org
When someone changes teams or managers in Smartrecruiters, the queues, ownership, or approvals in SendGrid update to match, so work reaches whoever holds the role now.
Onboarding: access ready on day one
A new hire recorded in Smartrecruiters creates the matching user in SendGrid with the right team and manager already set, so people can start working without waiting on a provisioning ticket.
What you can sync between SendGrid and Smartrecruiters
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| SendGrid objects | Smartrecruiters objects | How this pairing syncs | |
|---|---|---|---|
| Email Activity Synced with incremental and full sync per the Stacksync docs. | Candidates Person records with contact details, tags, attachments, custom properties, and consent; created, updated, and searched via the Candidates API, often populated from sourcing or enrichment pipelines. | Email Activity is specific to SendGrid and Candidates to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. | Contacts is specific to SendGrid and Applications to Smartrecruiters — each maps to any object or custom field on the other side. | |
| List Synced with incremental and full sync per the Stacksync docs. | Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. | List is specific to SendGrid and Jobs to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). | Segments is specific to SendGrid and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Categories Synced with incremental and full sync per the Stacksync docs. | Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. | Categories is specific to SendGrid and Interviews to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Senders Synced with incremental and full sync per the Stacksync docs. | Offers Offer records tied to an Application with status, custom offer fields, and offer documents; readable and writable, commonly synced to an HRIS on hire (documents endpoint limited to 2 requests/sec). | Senders is specific to SendGrid and Offers to Smartrecruiters — each maps to any object or custom field on the other side. |
How changes propagate between SendGrid and Smartrecruiters
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
SendGrid Smartrecruiters Sub-second propagation
DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.
DeliveryEach detected change is written to Smartrecruiters through its API, with automatic retries and rate-limit backoff.
Smartrecruiters SendGrid Sub-second propagation
DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
- Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.

FAQ
SendGrid and Smartrecruiters integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SendGrid and Smartrecruiters: authenticate both systems, choose the objects to sync (such as SendGrid's Email Activity and Contacts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means SendGrid and Smartrecruiters records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed SendGrid and Smartrecruiters connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom SendGrid–Smartrecruiters integration in-house.
-
Yes — Stacksync ships production-grade connectors for both SendGrid and Smartrecruiters. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on SendGrid: Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling. On Smartrecruiters: Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs; otherwise poll list endpoints with updated-after-style filters. No log-based change data capture. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the SendGrid side: Contacts, List, Segments, Categories, plus custom fields where SendGrid exposes them. On the Smartrecruiters side: Jobs, Job Postings, Interviews, Offers. Stacksync auto-detects both schemas and converts types between the two systems.
